With this number of SIDs in play I would consider the memory load that they will create. Perhaps the total memory defined for each exceeds real memory and you are forcing paging. This could cause an load on the server with processes timing out as all the SIDs fight for the IO to get their memory pages back in.
I've been off Solaris for a while so I can't quite remember the commands. swap -l perhaps? Another thing to investigate with is vmstat
If you set it running on one screen with vmstat 5 and make sure that the display is wide enough to display it all (statistics wrapped wrong a line are very hard to see a trend) and look at the Page section (check in the man page which it is) then on a second screen or using the OEM, fire in the request and watch what happens.
If this does cause paging, then you might be in a struggle to lower the memory definitions of each SID, but obviously keeping them running satisfactorily. You may be after purchasing memory at the end of this, if paging is the problem. Sorry.
I hope that this gives you a pointer. I would welcome any other suggestions though.

apache::session::oracle
Apache::Session::Oracle(3pm) User Contributed Perl Documentation Apache::Session::Oracle(3pm)
NAME
Apache::Session::Oracle - An implementation of Apache::Session
SYNOPSIS
use Apache::Session::Oracle;
#if you want Apache::Session to open new DB handles:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:sessions',
UserName => $db_user,
Password => $db_pass,
Commit => 1
};
#or, if your handles are already opened:
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh,
Commit => 1
};
DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the
documentation for Apache::Session::Store::Oracle for more details.
USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to
either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have
adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order
to make you think about this problem.
This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default
maximum is 8 KB.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
